IMPROVEMENT] IN 'ST'E'AM' PLOWING, AND SCRAPINQ ATTACHMENTS T0? CARS.

Specification forming. part of Letters Patent N 0. 189,961, dated April24, 1877 application filed February 3, 1 877.

To all whom it may concerns 7 y Be it known that I, SAMUEL T. SHANK-LAND, of Laramie, in the county of Albany and Territory of Wyoming, haveinvented a new andlmproved Steam Plowing andScraping Attachment to(Jars, of which the'following is a specification:

In the accompanying drawing, Figure 1 represents a plan view of myimproved steam plow and scraper for railroad-embankments;

Fig. 2, an end view of the attachment, shown in the act of scraping.Fig. 3 is a sectional side view of i one corner of the-car, showingmechanism in detail; and Figs. 4 and 5 are detail side and end views ofthe pulleys at the ends of'scraper-beams.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish, for the purpose of raisingrailroad-tracks and widening embankments, an improved steam plowing andscraping attachment to cars, by which the plowing and scraping can beaccomplished simultaneously with any number of plows or scrapers at bothsides of the track, and thereby the Work executed, by employing thepower of a locomotive with few hands, in very economical and rapidmanner.

The invention consists of a car with a centrally-pivoted plowcross-beam, having hinged scraper-beam extensions. A second car, withsliding beams guided in side boxes of the first car, is moved forwardand backward by a locomotive, and operates, by chains attached to theends of sliding beams and draw-head of the movable car, a number ofscrapers to and from the track, to carry the dirt up to the track afterthe ground has been plowed by the direct action of the locomotive andplows of cross-beam.

In the drawing, A represents a car, that supports at one end acentrally-pivoted plowbeam, B, which may swing into lateral position,and may be secured by suitable fastening devices therein, for attachingthe plows for work, or the plow-beam B may be carried into line with thelongitudinal axis of the car, when the work is discontinued. A secondcar, 0, with side beams D hinged to the end adjoining the plow-beam B,works the scrapers-in conjunction with car A, the beams D beingtaboutequal in length therewith,and guidedin. side boxes D of the carA,suitable catches a at the end of the sliding beams forming contactwith a cross-piece, b, of car A, to prevent the sliding beams from beingpulled out the boxes.

The cross-beam B is provided with hinged scraper-beam extensions B, thatmay be folded back over the same when the car is employed for plowing upthe ground at both sides of the wood, and thrown outwardly to be rigidlyattached to the ends of the plow-beam B by fastening-bands d. Thescraper-beams I) carry at their outer ends a guide-pulley arrangement,0, (shown in detail in Figs.& and 5,) over which chains E run, that areattached to the ends of the scrapers, and to the ends of the slidingbeams, and passed over pulleys e of the car, while chains E, that arestronger than the former, are applied to the sides of the scraper, andpassed over pulleys c of the car A to the draw-head of the car 0.

The chains E serve to pull the loaded scrapers up to the track, whilethe lighter chains E carry the empty scrapers back to be reloaded.

The front end of the engine is, coupled to the car 0, so as to move thesame, and thereby the sliding beams forward and backward. and workthereby the scrapers, the forward motion of the car drawing the scrapersin outward direction, while the backward motion carries them up to thetrack. I

The main car, with the cross-beam, is retained by the brakes in fixedposition} during the loading of the scrapers and discharging of thesame, the car being movedtoward the engine, by loosening the brakes, tosuch a distance that the scrapers take up the next load, when the brakesare again applied, and the scrapers moved up to the track.

The apparatus is worked, in addition to the men on the locomotive, byone man at each scraper, to fill and dump it, the same H1811.

handling the plows, and one brakman to work the brake on car withcross-beam, as stated.

The scraper-working chains have to be lengthened when working onembankments,

so as to provide for the increase in height.

The ordinary horse-scraper may be used, or heavier ones, if desired.

With an engine having four and one-half or five feet driving-wheels theapparatus may bring eight scrapers, four on each side, filled with dirt,to the trackiper minute, working equally effective on any curve orgrade, and accomplishing in this manner the work of one hundred men.

When the apparatus is used for plowing up the ground at both sides ofthe track preparatory to scraping and forming the embankment, thescraper-beams are folded back, and the plow-chains attached to theshorter and stronger cross-beam B, as shown in Fig. 1, the plows F beingdrawn over the ground by the direct action of the engine on the plowcar,so as to provide thus an efiective and time and labor saving apparatusfor widening embankments and raising railroad-tracks.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. The plow, made independent, and arranged in advanceof scraper, to work longitudinally with track, substantially as and forpurpose set forth.

2. A scraper for railroad-grading, receiving a back and forward motionfrom slides fastened to front and working in back car, substantially asand for the purpose specified.
